depends on what I'm drinking: beer gives me pleasant buzz, makes me a little more relaxed and talkative , and before I know it, I have to pee like never before.
Red wine makes me smarter. or makes me feel smarter, at least. Great for lounging about and watching films or such.
Whiskey is an interesting one: it has very little effect on my brain, but I loosen up a lot, and as a consequence, I lose a whole bunch of motor control and strength inhibition: once after a few whiskies, I had to go to the bathroom. After finishing my business, I reached for the toilet paper roll on a shelf right next to me, and promptly punched the bottom shelf off of the wooden bathroom cupboard said shelf was attached to. bit of a mess, that.
